    Is this the idle jet? Or?

    That issue where the motor sneezes after running for a while and then sitting seems to be common on those engines. It is on my '98 Johnny 150HPV6. A work around is to start the sneezing engine and keep her idling high enough in neutral to keep running for a few minutes. After that she should...

    115hp 2 stroke and quick connects.

    Different quick connects use different fuel lines. You need a quick connect for 3/8" fuel line. Make sure the quick connect seals when disconnected, or it will suck air into the fuel system. You might use a fuel selector valve instead. A much better idea as they should seal well.

    1980 Inline 4 80hp power tilt/trim

    The PTT unit from a mid 70's to mid 80's Merc inline 4 or 6 should fit your motor. The PTT unit consists of two trim brackets, two trim cylinders, a pump/reservoir unit that mounts in the boat and w/ hydraulic lines to power the PTT cylinders. While it does work, it is pretty obsolete and...

    1988 115 Inline 6 Fuel Pump

    The Crowleymarine web site shows a figure 8 pump style for that IL6 serial number. It is roughly the shape of the old baseplate. Here is what it looks like. https://www.nlamarine.com/products/mercury-outboard-fuel-pump-assembly-66530a6-13727a1-90hp-115hp-140hp-6cyl-66529?variant=1138636028...

    Outboard wiring conduit

    They make a black plastic tubular mesh as well. A lot of outboard OEMs use it. Dingbats suggestion is a good one. However, I have had that kind of tubing fail from the sun in a year or so. Make sure it is UV resistant.

    cooling system 1999 mercury 150hp 2 stroke

    Zoomie: A 1978 Merc 150HP engine would be the one of the early V6 models. Those have two thermostats each. The last 150HP inline 6 was 1977. These did not have thermostats. JRB: The water outlet of the impeller should go into a copper water tube. When you install a new impeller, you use the...

    1983 merc 115 how to link and sync

    A Mercury Service manual is a real good idea, as the procedure has some details. 1 Synch carbs to open at the same time, using adjustment on plastic levers connecting carb throttle plates. 2 Remove spark plugs 2-6 and put timing light on #1. Remove prop. Set throttle such that carbs are still...

    Hoist engine to remove steering cable? 2001 Starcraft 176

    I think you are very close to getting the steering cable off, w/o moving the engine. Disconnect the cable at the steering wheel end and pull some slack into the splashwell. Now see if you can get the steering rod out of the tilt tube. If not, you can slide the engine to the port side and get...

    1979 80 hp Mercury swap out

    First the control must push the throttle closed in neutral. Second the idle stop screw must be set correctly. Third, it sounds like you need a Mercury Service Manual for your motor. It will have all the specs you need.

    Cold start issues

    Most Merc controls have either a separate push button for choke or push the key in for choke. Your motor has the electric solenoid, but the drawings are unclear if you have a traditional choke plate or enrichener. It doesn't really matter much as both work fine. Remember when cold starting...

    1979 80HP Mercury

    Disconnect the shift cable at the engine. Now when installing the gearcase, move the shift slider a bit to mate the upper and lower shift rods.

    1990 mercruiser 4.3 no spark

    Sure that is compression stroke half the time. The cylinders fire every 720* of rotation in a 4 cycle motor. You might pull the distributor, rotate the engine 360* and reinstall it pointing to #1 spark plug wire.

    1979 80HP Mercury

    The best way is to have both gearcase and control in neutral. From my other post: There is a molded plastic fitting that holds the upper shift rod in place, in the midsection. They often fall into the gearcase where they do not function, or they get lost. If you have this fitting, make sure it...

    1979 80HP Mercury

    Spinning one way with a rachet sound means the gearcase is in forward. Use a crescent wrench to gently turn the lower shift rod CCW until it clicks into neutral.

    1979 80HP Mercury

    It is best to install the gearcase in neutral, as lower shift rod is in a single position, not a range as in forward. Obviously the control needs to be in neutral as well.

    Don't tape holes.

    Wet sanding paper can minimize the clogging of sandpaper. I bought an air powered orbital disc sander. It uses velcro fasteners The paint on my speedboat melts when sanded, so the cool wet sanding works. When I removed the decals of my outboard hoods and midsections, I used a heat gun...

    The midsection on my '93 Merc 135HPV6 has cracked

    OK a slight correction the Permatex was the no. 3 type. I was putting it on the bolts to my poppit valve, when the wind blew and caused a bead on the midsection. Boy I am glad it is not a crack.....

    Bought Boat and Steering is locked up

    Dub, you do realize that the steering rods bind in the tilt tube far more often than they fail? I think it worth a look, as it would only take .05 worth of grease to fix it, once it is loose. Of course it will take a can of penetrating oil, a pipe wrench, an hour and some rags, plus maybe...

    The midsection on my '93 Merc 135HPV6 has cracked

    Actually, in the morning sun, vs dusk, it was a long thin drip of Permatex no 1 sealant. It was so consistent and long it sure looked like a crack and passed the fingernail test. F-troop back to normal.
